ATTACHMENT FOR TRACTORS Filed June 5, 1925 2 Sheets-Sheet 2 IIIIAVIII Patented Oct. 22, 1929 UNITED STATES THOMAS H. JACOB, OF WAUSAU, WISCONSIN ATTACHMENT FOR TRACTORS Application led .Tune 5,

This. invention relates to improvements in attachments for tractors.

One ot the objects ot my invention is the provision of an attachment Yfor standard tractors such as a Fordson and is particularly in the manner ot a take-oit' whereby the power of the tractor may be used for diiierent purposes and wherein nearly all the standard parts of the tractor are used with the exception of a very small change in the construe tion.

Another object of the invention is the provision of an attachment ot the above type in which the clutch control can be very easily and gradually operated to couple the load to the engine, and in which an adjustment is provided for this clutch control, such adjustment being accessible from the outer side of the complete device so that it may be finally adjusted after the complete assembly has been made, thus securing the accurate tinal adjustment so much desired in this type ot work.

An embodiment of this invention is shown in the accompanying drawings, in which Figure 1 is a side elevation of a Fordson engine with parts in section showing the at tachment in place.

Figure 2 is a front end view ot the device, such view being partly in section.

Figure 3 is a section view on the line 3--3 ot Figure 1.

Figure 4 is a section on the line 4-4 ot' Figure 1.

Referring to Figures 1 and 2, it will be seen that a front support 1 has been provided which tits between the front lugs 2 of the tractor engine 3 and replaces the iront axle. This support 1 is coupled to the front lugs by means ot a pin 4 and is provided with divergent legs 5 terminating in attaching feet 6, which may be secured to the floor.

A pair ot bolts are threaded into outwardly projecting arms 8 of the support 1 and are locked in place by means ot lock nuts or locking collars 9, as shown most elearly in Figures 1 and 2.

The rear end ot the engine is supported by means of a relatively large casting which has a hollow part or casing 10 provided with 1925. sei-m1 No.` 35,149.

a pair of divergent legs 11 equipped with attaching feet 12. This casing surrounds theiiywheel 13 of the engine and houses a shaitt 19 which is supported at one end by ball bearings 14 carried by the flywheel and at the 55 other end by ball bearings` 15 carried by an outwardly projecting extension 1G ot the housing 10, such extension projecting beneath the overhanging portion of the pulley 17 and being in close proximity to the hub 18 of such 5o pulley. This shaft is provided with a splined portion 20 engaging the pulley and is provided with a threaded portion 21 upon which the lock nut 22 for the pulley is screwed. The usual Fordson clutch 23 is. employed and is c5 positioned within the recess 24 in the flywheel in the usual manner. It is operated by means of a lever 25 which is provided with an elongated aperture 26 (see Figure 3) which loosely surrounds the shaft 19. The lower end of this lever is provided with a recess 27 within which the pointed end of an adjusting bolt 28 tits, such adjusting bolt being screwed through the housing 1() and locked in place by means oi' a loch nut, as shown most clearly 75 in Figure 1. The upper end of the lever `25 is similarly provided with a recess 29 to receive the pointed end ot' the controlling screw 30, such controlling screw being provided with an external handwheel 31 where so by the clutch may be operated.

It is to be noted from Figure 4 that the lever 25 is provided with a pair of lugs 32 which are attached to the lugs 33 of the standard clutch 23. s

In assembling the device, it is to be noted that the rear casting or housing 10 is secured in place and the front support is at tached by means oi the pin 4 thus giving a three point suspension for the engine and 9o securing the engine in position without stressing any of its parts. Thereafter, the screws 7 (see Figure 2) are adjusted to engage opposite sides of the front of the engine and are then locked in place thus giving a very secure and iirm support.

The exact adjustment i'or the clutch is initially secured by adjusting the bolt 28. Thereafter, the device may be operated by manipulating the handwheel 31 to gradually 100 apply t-he load or disconnect it, as desired.

It will be seen that a very simple and effective type of attachment for a standard tractor engine has been provided which employs practically all of the moving parts of the engine and driving pulley, and which may be'easily-v and quicklyapplied even by an unskilled'V operator;

It will be seen further that a very effective support has been provided which permits accurate alignment with subsequent positive locking in position.

It will be seen further that a very easy control has been provided for applying and disconnecting the load and that this control for the clutchmay befvery; quickly and sim,- ply. operated.,

Although the inventionv has been described inconsiderable detail, it isyto be understood that thev invention, may begivariously embodied and is, therefore, tof bef limited only as claimed. A

Iclaim:

The combinationl of driveny flywheel, a shaft extending* axially` of said flywheel, a roller bearing interposed between said flywheelf and shaft, a; supportA adjacent the outer end of saidA shaft, a clutch interposed between said flywheel andi; shaft,l an operatingl lever for controllinggsaid clutch, said lever extending transverselygo-f said shaft and apertured to: permit the passage ofy said shaftytherethrough, said lever having: a recess at one end, an adjusting screw having a pointed end bearing 1n said recess and'l constituting a fulcrurnvfor saidl lever'7 a controlling screwhaving `a pointed end loca-ted in the-other recessof saidlever, anda casing for said clutch and lever, both said screws; beingthreaded through said casing'.` Y
